  • The Sensor Node

    At the heart of the system is the Sensor Node. Integrated into each luminaire during manufacture, each Sensor Node contains a motion sensor, infrared transmitter, infrared receiver, ambient light and intelligent microprocessor. Here's how it works:

  • 01

    The moment a Sensor Node detects occupancy, the luminaire responds by outputting a predetermined light level (for example 100%). It simultaneously communicates that it can see someone to its neighbouring luminaires using a level 1 proximity-limited infrared signal.

  • 02

    On receipt of this level 1 signal, neighbouring Sensor Nodes know someone is located within one light fitting of them. They respond by outputting a predetermined light level appropriate to an occupant in that vicinity (e.g. 80% brightness), and simultaneously relay a level 2 signal to their own neighbours, informing them there is an occupant two light fittings away.

  • 03

    This communication propagates rapidly throughout the floor, creating the Occupancy Information Cloud. Each Sensor Node knows at all times how close the nearest occupant is, and can adjust their light level accordingly. The Occupancy Information Cloud contains rich occupancy information that is real time, and position specific.

The result is comfortable lighting conditions around all occupants, lower light levels in areas adjacent to them, but importantly no wasted lighting of unoccupied or naturally lit areas. Once an area becomes vacant, each light gently dims to a low light state until the system is sure that nobody remains in the area. After this time, the lights switch off completely.

The system is completely plug and play, and intrinsically adaptable to changes in the layout of the Sensor Nodes or office. However, Organic Response can be highly optimised via a simple smartphone app. This allows individual luminaire settings to be easily adjusted for the specific needs of a particular occupant or environment.

For example, brightness can be trimmed and dwell times increased or reduced. In addition, using the same infrared peer-to-peer communication network described above relay configuration allows a whole floor to be configured with a new setting just by pressing a few buttons on the smartphone. With no training, electricians, facility managers, office managers or even each occupant has the ability to configure and optimise the system’s behavior to suit their individual needs.
